Devrim Lingnau was born in Mannheim in 1998 to a German mother and a Turkish father. While still at school, she attended the Academy of Dance at the Hochschule für Musik und Darstellende Kunst in Mannheim. She made her acting debut in 2014 in some reenacted scenes of the true crime show "Aktenzeichen XY... ungelöst!". A little later she got her first leading role in the third and fourth season of the youth mystery series "Fluch des Falken" (2014-2015), as a peppy German-Turkish girl. In the much praised two-parter "Verlorene Sicherheit" (2017), an episode of the crime series "Unter Verdacht", she was also cast to play a German Turk. She had guest roles in the TV series "Die Kanzlei" (2017) and in the web series "Immortality" (2017).   

After graduating from high school in 2017 Lingnau stood in front of the camera for her first leading role in a feature film: In the British production "Carmilla", a romantic mystery drama, she played the title role. The premiere took place at the Edinburgh International Film Festival 2019. Also in 2019 she appeared in the TV crime thrillers "In Wahrheit: Still ruht der See" as a member of a mysterious youth clique and in "Der Bozen Krimi - Gegen die Zeit" as a young kidnapper. She then had a leading role in another feature film, "Auerhaus" (2019, directed by Neele Leana Vollmar), about a clique of high school graduates who start a rural flat-sharing community full of idealism but soon are faced with the limits of their shared dream.
